J5 Track Assembly Part 02

Parts all from current Club drawings

In this tutorial we will add the front drive and idler pieces to the assembled butterfly plates.

-- Only one track is shown There are two identical tracks required.

Butterfly Plates after assembly in Part 01

Attach a ¾” heavy retaining ring to one end of the front axle.

Insert the axle through one bearing and about half way through the butterfly plates.

This is the inside bearing cap. We thread on a wavey washer and a spacer. The wavy washer will be against the bearing race when assembled.

After sliding the wavy washer and spacer inot the recess, the spacer will extend jsust slightly beyond the inner bearing cap.

Slide an idler wheel onto the shaft. Clamp ring towards the inside, but leave it loose for now.

Slide the drive sprocket onto the shaft next. Do not forget to include the shaft key, and it also remains loose at this time.

Add the track drive sprocket at this point. Include the shaft key but do not tighten.

The remaining front idler is now added. Do not tighten.

Add a spacer and then wavy washer. They will set the gap between the idler and the bearing cap as before.

Work the axle through the next bearing and secure with a heavy retaining ring.

The idler wheels are tightened against the spacer/wavy washers, then the sprockets are tightened against the shaft keys. The motor and chain are added later.
